Saturday night
Most places will be dry overnight as slack high pressure remains across the country. A few drizzly showers moving into western Scotland as weak fronts drift in from the Atlantic.

Sunday
High pressure across southern Britain brings a fair day to much of England & Wales. Good spells of sunshine, best around coasts in the afternoon. Light winds and sea breezes. A freshening south-westerly breeze in the north-west of Britain & Ireland brings a risk of a few drizzly showers, but amounts small, and areas east of high ground should stay dry.

Monday
A dry, sunny and very warm Bank Holiday for much of England & Wales. Sunshine turning hazy as cloud builds from the west.

Freshening south-westerly winds. 15 to 18C north, but up to 23 to 27C south & east.
